Avoid detonation, detonation is not always audible so always run octane equal or higher to the tune. Forget the 2%+-. Go for the pump octane that matches the tune, your trucks health depends on it.

If your using 91 SCs tune, Use the 93 octane. Our pistons don't like detonation and SCs likes to make these engines detonate. The real problem is if you hear it detonate at wot it's usually to late the pistons broke, Usually.

yeah i have seen way to many of them......run 93 octain all the time even with a stcok tune. and you will not have to worry about the detination

EDIT i know of 2 people in this thread that had broken pistons, and i was there both times they were discovered. i have a motor in my gerage that looks worse than than the one pictured out of my buddys truck. its a really common thing run any tune you want but run 93 OCT
